The TAJE227K016RNJV: This is a 220 µF molded tantalum capacitor rated at 16 V with 500 mΩ ESR at 100 kHz — a common choice for bulk decoupling on a 12 V input rail where the ripple current stays within the capacitor's dissipation limit. The 500 mΩ ESR sets the self-heating under ripple current: at 1 A ripple, the internal power dissipation is 0.5 W, which must be checked against the package's thermal impedance to stay within the 2000-hour lifetime at 125°C.
2917 footprint and temperature range
Housed in the 2917 (7343 Metric) case, size code E, measuring 7.30 mm x 4.30 mm with a seated height of 4.30 mm — this is a standard tantalum footprint that matches many existing PCB layouts.
